A nurse is reinforcing teaching about the use of an insulin aspart 70/30 pen with a client who has type 1 diabetes mellitus. Which of the following statements by the client indicates an understanding of the teaching?

"I will hold the pen upside-down to select the appropriate dose."

"I will apply a disposable needle on the cartridge."

"I will aspirate before injecting the insulin."

"I will shake the pen before injecting the insulin."

Answer and Explanation

The Correct Answer is B

A. "I will hold the pen upside-down to select the appropriate dose.": Insulin pens are designed to be held upright with the needle pointing upward when selecting the dose. Holding it upside-down can cause air bubbles to enter the cartridge and result in inaccurate dosing. Correct technique ensures the client receives the intended insulin amount.

B. "I will apply a disposable needle on the cartridge.": Attaching a new disposable needle for each injection is essential to maintain sterility, prevent infection, and ensure accurate dosing. This practice also prevents needle damage and reduces the risk of insulin leakage during administration.

C. "I will aspirate before injecting the insulin.": Aspiration is unnecessary with subcutaneous insulin injections and can cause tissue trauma or discomfort. Current guidelines advise inserting the needle directly into subcutaneous tissue without pulling back to check for blood.

D. "I will shake the pen before injecting the insulin.": Shaking insulin aspart 70/30 can create air bubbles and compromise the insulin mixture. Instead, gently rolling the pen between the palms ensures proper mixing without introducing bubbles, preserving insulin effectiveness.

Correct Answer is ["A","B","C","E"]

Explanation

A. Pierce the puncture site quickly: The puncture is performed after proper site preparation and drying to minimize pain and reduce the risk of contamination. A quick puncture ensures adequate blood flow and less tissue trauma.

B. Allow the site to dry: After cleansing the site with an antiseptic swab, allowing it to air dry prevents alcohol or antiseptic residue from contaminating the blood sample. Residual moisture can interfere with test accuracy and cause stinging.

C. Cleanse the site with an antiseptic swab: Proper cleansing reduces the risk of infection at the puncture site. The site should be wiped using a circular motion and then allowed to dry completely before puncturing.

D. Apply blood to the test strip: Once a sufficient blood droplet is obtained, it is applied directly to the glucose test strip for accurate measurement. Proper application ensures the meter reads the correct glucose concentration.

E. Squeeze the site gently to obtain a blood droplet: Gentle pressure helps produce an adequate blood droplet without causing tissue trauma or hemolysis. Excessive squeezing can dilute the sample with interstitial fluid, affecting accuracy.

A. Dextrose 5% in water B. Dextrose 5% in 0.45% sodium chloride C. Lactated Ringer's D. 0.9% sodium chloride

Correct Answer is D

Explanation

A. Dextrose 5% in water: D5W contains glucose, which can cause red blood cells to swell and hemolyze during transfusion. Hemolysis increases the risk of acute transfusion reactions and reduces the effectiveness of the transfused cells. This solution is therefore unsafe to use as a carrier fluid for blood products.

B. Dextrose 5% in 0.45% sodium chloride: The presence of dextrose again creates a risk of hemolysis because glucose alters the osmotic stability of transfused RBCs. The hypotonic component further increases the likelihood of cell rupture during administration. This makes the solution incompatible with packed RBC transfusion.

C. Lactated Ringer's: LR contains calcium, which can bind with the anticoagulant citrate in stored blood products. This can cause clot formation within the infusion line or blood bag, creating a serious safety risk. For this reason, LR should not be used when administering packed RBCs.

D. 0.9% sodium chloride: Normal saline is isotonic and does not interact with the anticoagulants in stored blood, making it the safest and recommended solution for RBC transfusions. It maintains cell integrity and prevents clotting, ensuring the transfusion can be delivered effectively and without complications.
